IMPROVEMENT IN .COMPRESSORS FOR FLIERS IN SPINNING-MACHINES.

Specification forming part of Letters Patent- No. 42,620, dated May 3, 18(34.

To all whom it may concern.-

-Be it known that we; SIMEON GOODWIN and JOHN A. EMERY, of Biddeford, in the county of York and State of Maine, have invented a new and useful improvement in compressorsused in the manufacture of cotton ""Gorresponding 'lettersrefer to corresponding parts.-

In Fig. 1, f is a common flier, having atube, zz, on the inside of eacharm or upper section for conducting the roving to the bobbin after it passes through the flier-nose a. B is a bobbin having heads h h, and standing on the spindles S. Our improved compressor'c is attached to the flier f by the spring g, which spring causes it to press constantly on the roving on the bobbin while the same is being filled. The compressor 0 has a shoulder, 0, near where it is attached to the flier f, and a hole, V, .in its flattened nose 1;. Along the back or outside of the compressor, between the shoulder o and hole V, is a groove out in the body of the compressor for the roving to run in, and which prevents it from falling down and coming in contact with the head of the bobbin.

The method of filling a bobbin is as follows: The spindle S is connected with mechanism .(not shown) which causes it to revolve from, and also gives it'a reciprocating vertical motion, or causes it to rise and fall alternately the length of the bobbin B, which is so attached to the spindle as to revolve and rise and fall withit. The flier ff is also attached to mechanism which causes it to revolve from left to right or in the same direction with the spindle S, the flier and spindle being driven. at difi'erent rates or speed, or one leading the other, in a manner well un- The roving is then passed through theflier nose a and tube a, down to the compressor, 0, around which it is coiled, and then hooked or caught over.

the shoulder 0, from which it is passed along the groove in the back of the compressor and through the hole V in the pad 19. Now, when the bobbin and flier are caused to revolve and traverse, as is above described, the roving will be drawn through the tube z, around and along the compressor 0, through the hole V, and wound upon the bobbin B, which is represented as partly filled. The use and object of acompressoris to apply apressure to the roving on the bobbin by the action of the spring g, so that each successive layer is wound on while all the layers under it are under pressure, by which means a very much larger amount of roving can be put upon the bobbin, thus rendering its. use very desirable. It is also desirable to use a roving-bobbin with the heads h h, as it will be readily seen that such a bobbin will hold much more'than a' common roving-bobbin, which is constructed without heads, the ends being slightly conical, but with the compressors in common use this has been found exceedingly difficult for these reasons.

A common compressor, 0, Fig. 2, is usually made with-a round body of nearly the same size the entire length between the flier and the flattened'part p. 'The roving after passing downthe tube 2 is coiled several times around the body of the compressor before -beingcarried through the hole" V in the pad 10, which pad is much wider than in our improved one. The roving by being coiled around the compressor, as shown, is very liable to be brought in contact with-the head h, at or near the point as, and immediately broken unless the point or pad 10 is made very wide, 'so as to strike the heads h h of the bobbin as it traverses, and thus protect it. But the objection to making the flattened part 10 wide is that the roving is thereby prevented from being wound under pressure as near to the heads h h as is desirable, the roving being delivered to the bobbin through the hole V, 1

which is in the middle of the pad, so that where a wide pad is used, the hole being in the center of it, the roving could not be wound properly at the ends of the bobbin on account of the pad coming in contact with the heads h h,- but these objections and difiiculties are entirely overcome by the use of our invention. The shoulder o of our improved compressor,

Fig. l, is situated so at from the pad 10- that when the roving is passed over it, as-shown,

and conducted along the groove to th e hole V, it is keptentirely out of the way of the heads h h, and is thus prevented from being broken thereby, while at the same time a very narrow pad can be used, bringing the hole V or point of delivery nearer the bobbin-heads than any other arrangement will admit of-adm-ntages which, in conjunction with being able to use a headed bobbin, will be readily understood and appreciated by all practical manufacturers of cotton. We have accomplished the same results by the use of an equivalent means, which consist in constructing the body of the compressor a little wider than its average size at the part where the resisting guidin gsurfaces or shoulder 0 is located, and making a hole in the widened part-through which the roving passes and is carried along the back of 'the compressor and through the hole V, as desciibed, and shown in Fig. 3 of the supplemental drawings; but the difficulties attending this method were numerous, a principal objection being the threading, or putting the roving through the hole, though this was partially obviated by cutting a slot 'dr opening from the hole to the side or through the side of the compressor, through which the roving could be passed into the hole laterally.

We are aware that compressors such as show-u in Fig. 2 are not new, and that they have been made with alip or strengthener, a, opposite the hole V, which has been used to strengthen the pad 1) when it has been made narrower than is there shown, or as is more fully shown in Fig. 5 of the supplemental drawings, and with a lateral opening or slot, 1', running from the hole V to or through the side of the pad 19, which is opposite to the said lip or guard-rib a, as described in the patent of WV. H. Thompson and It. H. Plumnier, granted the 19th day of July, 1853, and numbered 9,865; but the invention of the said Thompson and Plummer isditi'eren-tfrom ours, and does not accomplish the same important results. They sought to so constructs compressor having aside slot or opening, i,-lI 1 the pad, that it could be used in fillin g a roving bobbin with two heads. To accomplish this and wind the roving under pressure as near to the heads as possible, it is necessary to make the'pad p narrow; but a very narrow pad when made with the slot he too weak, and

very liable to be broken.

To strengthen the pad and protect theroving from the action of the bobbin-head, a guard-rib, a, as shown in Fig. 5 of the supplemental drawings, is used by them. Where their compressor is used, the roving passes spirally around the body cof the compressor, in the usual manner, but itis, in fact, no more protected by the it is in a compressor without such a rib, as the heads of the bobbin extend far beyond the rib, and in actual operation the heads guard-rib a described than have a vibratory motion, which brings them into contact with the thread of roving, where it is wound around the body of the compressor within reach of the said heads, thus destroying it.

In the Thompson and Plummer compressor, construe-ted as described, with a guard-rib, a, opposite the slot 'i, protection, at most, is afl'orded from only one of the bobbin-heads, as when the bobbin traverses, so as to bring the slotted side of the pad against one of its heads, the guard-rib or strengthener a being opposite the slot, or on the other side of the pad, the roving thread is unprotected.

In our invention we use no guard-rib in the vicinity of the hole V, in the pad 10 in the sense it is used in the Thonnpson and Plummer compressor aforesaid. We pass the roving through the body of the compressor, near the heel or flier end of the same, as shown in the supplemental drawings, Fig. 3, or around a shoulder, 0, Fig. 4 of said drawings, located at the flier end of our compressor, and thence along a groove runnin g along the middle of the back of the body part of the compressor to the hole in the pad 10, as shown, perfect y protected from the vibratory action of both heads of the bobbin. B y thisarran-gemcnt we are enabled to use a very narrow pad, so as to wind the roving under pressure-close to the heads, which can-not be done where the patented compressor described is used, as is well known to all practical manufacturers using the same.

In nearly-all compressors the roving-thread on'the way to the bobbin passes around the body of the compressor spirally, as shown in Fig. 2. In our improved compressor, the directiorn of the roving-thread being wound onto the bobbin is changed at or quite near to the hecl or flier end of the compressor, and at a distance from the pad of the same, from a spiral movement around the body of the com ressor to a movement in a direct line along the back or outside of the body off the same. We therefore lay no claim what soevcr to aniything shown and described. in the patent of the said Thompson and Plummer; but

We claim- Changing the direction of the thread of roving being wound onto the bobbin at-or near the'hee'l or flier end of the compressor from a spiral movement around the body of the same to a horizontal direction or movement along the back or outside of the body of the compressor, and conducting the said thread (when such a change is made in the direction of the 'inovements at that point) along the body'of the compressor protected from both heads of the bobbin, substantially in the man- 'nerend for the purposes specified.
